SPOKE-EXTRACTOR.

Specification of Letters Patent.

Patented April 14, 1908.

T 0 all whom it may concern:

Be it known that I, DAVID L. WILLIAMS, a citizen of the United States, residing at Trenton, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Spoke-Extractors, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an improved spoke extractor, and I declare that the following is a full, .clear, concise and exact description thereof sufficient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings in which like letters and numerals refer to like parts I throughout.

In the drawings Figure 1 is a side view of the extractor in operative position relative to a hub and spoke; Fig. 2 is a top view of the extractor; Fig. 3 is an inner end view; Fig. 4 is a cross section view on the line 90-95 of Fig. 1, and Fig. 5 is a plan view of a portion of the device on the line y-y of Fig. 1.

It will be understood that in using the extractor the hub is supported in the usual manner on a stand towhich it is secured by a screw-bolt for the application of leverage to hold the hub firmly seated, and that the outer end of the spoke may be supported by a rod, brace or other means.

Referring to the drawings in detail, A represents the hub and A the spoke which is to be extracted. The device comprises ower means for clutching the spoke and similar means engaging the former means to extract the spoke. The former means comprises a yoke B of suitable form and strength, having at its base a properly formed recess to engage one side of the s oke. To bear on and clutch the other side of the spoke I provide block 0 which is adapted to slide within the yoke on the sides I) and which is operative by the screw or bolt 6 to which power is applied to force the block C toward the opposite end or butt of the yoke B (pro erly recessed for the spoke) and securely hol tween. 1

The block 0 has a threaded a ceive the lever erture to reor power rod D w ich is screwthreaded to be assed to and fro through the block 0 and w ich has at its outer end the lever with handles D and at its inner end the head (1 fixed on the end of the lever or power rod by a loose joint of common construction d the spoke therebe- 1 so that it can bear evenly on the surface of the hub adjacent to the spoke that is to be extracted. Connected with the yoke B and here shown as integral with block C is the support arm B which extends parallel with he lever or power rod D and at its outer end is adapted by the offset 6 to support the lever or power rod in its manipulation. Upon the support arm is slidingly mounted a guide bracket E having yoke portions E to receive the spoke whereby the mechanism is held in position for its operation. The bracket has the upper members of the bracket may be slightly drawn together to engage the brace arm B to prevent the bracket from slipping.

In operation the device is slipped onto the spoke, as indicated in Fig. 1, the lever or power rod being'unscrewed so that the yoke can be brought suitably near the hub, the spoke lying between the bottom of the yoke and the sliding block which is carried in the yoke. The block is then screwed downward to engage the spoke between the block and the yoke. The outer end of the spoke lies between the yoke arms of the sliding bracket E whereby the device is kept from swinging to one side and is supported in a measure on the spoke so that the power is utilized to the best advantage. By means of the handles D the lever or power rod D is then screwed inward so that the head 03 bears against the hub and the power rod is operative towithdraw the spoke.

It will thus be seen that I have provided a simple device comprisin means for clutching the spoke and means for pulling the same from the hub, whereby the spoke can be extracted without any marring of the hub or chipping the edge of it next to the spoke.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A spoke extractor comprising the following members in combination: a rigid support-arm having at one end an offset apertured to loosely support a power rod and at the other end having a block screwthreaded to receive the said rod, the face of such block being adapted to engage one face of a spoke, a yoke transverse the arm and having side-bars engaging the block and having the interior face of the yoke, opposite the said block, adapted to engage the other face of the spoke, a screw-bolt mounted in the offset at one end and a block at the other handles and being screw-threaded for a part of its length, a block adapted to engage a spoke and screw-bored to receive the said rod, an arm connected with the block and extending parallel with the power-rod and having an ofiset to support the power rod adjacent its outer end, and a yoke having a face 2. In a spoke extractor, an arm having an ada ted to engage the spoke and mounted on the lock adjustably transverse the line of the spoke.

6. A spoke extractor comprising a powerrod, an arm substantially arallel with and along the side thereof having at one end a block, the said block being screw-bored and yoke and adapted to fix the relative position of said engaging faces, and a powerrod screw-threaded at one end through said block and su ported adjacent the other end in the said 0 set, one end of the rod having means bearing on the hub and the other having lever handles to turn the same.

end, a power-rod su ported loosely near one end in the said 0 set and screw-threaded near the other end through the said block, having at the former end handles and at the other end means to bear on the hub of a wheel, and a yoke mounted, on the adjacent end of the arm having a spoke-engaging surface, the face of said block also having a spoke-engaging surface, and a bolt screwmounted in the yoke adapted to clamp the spoke engaging faces against the spoke.

3. A spoke extractor com rising a owerrod bearing at one end on t e hub ad; acent the spoke and at the other end having handles and screw-threaded for a part of its length, a block adapted to engage a spoke and screw-bored to receive the said rod, a yoke having a face ada ted to engage the spoke and mounted on t 1e block adjustably transverse the line of the spoke.

4. A s oke extractor com rising a owertured offset, the power-rod passing through said screw-bored block and the said offset and adapted to bear on the hub at one side of the s oke, a yoke formed to slide on the block, t e latter being fashioned to receive the yoke, and having means to adjust the yoke relative to the block to engage a s oke between the o posite face of the yoke and the block, by WlElClfl combination power against the hub at one side of the spoke to withdraw the same.

7. A spoke extractor having an arm provided at one end with a block screw-bored, a power-rod passing through the said block and adapted to bear on the hub at one side of the spoke, a yoke mounted on the block adjdustable transverse the line of the an rod bearing at one end 'on t e hub a jacent the spoke and at the other end having handles and screw-threaded for a part of its length, a block adapted'to engage a spoke and screw-bored to receive the said rod, a yoke having a face adapted to engage the spoke and mounted on the block adjustably s oke rovided with means engaging the b lock to c utch the spoke between the block and yoke, and a bracket adapted to engage the spoke and the ower-arm.

In testimony wl iereof I aihx my signature in presence of two Witnesses.

transverse the line of the spoke, and a bracket slidably mounted and engaging the power-rod and the spoke near its free end.

5. A spoke extractor comprising a powerrod having at one end a loose joint adapted Witnesses: for the bearing of the rod on the hub ad- F. L. WORDAN, jacent the spoke and at the other end having J. S. JONES.

the said arm having at its other end an aper-' may be applied through means of the rod
